Self-feeding paint brush

Abstract

A self-feeding paint brush of the type comprising a housing, an upper deck, a paint container, a transmission mechanism and a brush assembly, wherein a control switch is made on the brush assembly to turn on a motor to drive a gear set to operate via a pinion and a driving gear, causing a suction chamber to suck up oil paint from the paint container into a guide tube via two ducts, for further distribution over the bristles of the brush assembly through a nozzle tube. The housing is releasably secured to the paint container at the top by a hook-and-ring connection to facilitate oil paint filling operation.

What is claimed is: 
     
       1. A self-feeding paint brush of the type comprising a housing, a transmission mechanism, a paint container, an upper deck and a brush assembly, characterized in that: said housing comprises at the outside two hooks on two opposite, recessed portions, and at the inside a motor mounting chamber, said motor mounting chamber having a suction tube extending downward at the center, a battery chamber for holding a battery set, and a power socket connected to said battery set, and a plurality of internally screw threaded columns;   said upper deck comprises a plurality of internally screw threaded columns for connection to the columns of said housing by screw means, a battery cap releasably disposed to cover said battery chamber, and a recessed flat surface at the top, said recessed flat surface having two through-holes made thereon;   said transmission mechanism is comprised of a motor holder, a control block and a mounting plate respectively connected together, said motor holder having two notches at two opposite ends, a plurality of bolt holes and a motor attached thereto at one side for driving a driving gear through a pinion, said control block having two notches at two opposite ends, a suction chamber defined therein for mounting a gear set, said gear set being carried to rotate by said driving gear, a plurality of through-holes corresponding to said bolt holes on said motor holder, and two ducts respectively disposed at two opposite ends of which the upper duct is fastened in either one of the two through-holes on said recessed flat surface of said upper deck and the bottom duct is connected to said suction tube, said mounting plate having a plurality of projecting strips transversely extending therefrom at the top and the bottom and respectively disposed to press on the notches on said motor holder and said control block for retaining said motor holder and said control block, and a plurality of countersunk holes respectively made at locations corresponding to the through-holes on said control block and the bolt holes on said motor holder for connection by a plurality of screw bolts;   said paint container has two retainer loops on two raised blocks at two recessed portions on the outer wall surface thereof at two opposite ends for engaging with said two hooks of said housing permitting said housing to be secured thereto at the top;   said brush assembly comprises a casing formed of two symmetric shells, having a connecting end for mounting a brush, a stepped hole at the inside for mounting a guide tube, a control switch connected to said power socket through an electric line to control the operation of said motor, said electric line being inserted through one of the two through-holes on said recess flat surface of said upper deck and electrically connected to said power socket, said guide tube having one end inserted through the other of the two through-holes on said recessed flat surface of said upper deck to connect to said suction tube through the two ducts of said control block and an opposite end inserted through said stepped hole and secured in place by a collar for connection thereto of a nozzle tube, said nozzle tube being concealed in a plurality of bristles fastened in said brush for distributing oil paint from said paint container over said bristles.
